QUESTION:

A mass attached to the end of a spring is stretched a distance .v0 from equilibrium and released. At wrhat distance from equilibrium will it have acceleration equal to half its maximum acceleration?

ANSWER:

Step 1 of 2

The attached mass is released from the equilibrium, then the equation is given by

                                                        

Here, is the initial distance, is the stretched distance,  is the angular frequency and t is the time.

The acceleration of the mass is given by

                                                       

Here, is the acceleration,  is the maximum acceleration,  is the angular frequency and t is the time.

If the acceleration is half the maximum acceleration at a distance  from the equilibrium,
